Journal ArticleDOI
Growth of aligned ZnO nanorod arrays by catalyst-free pulsed laser deposition methods
TL;DR: In this paper, a set of well-aligned ZnO nanorods were synthesized on a Si substrate at 600 °C by 193 nm pulsed laser ablation of a target in low pressures of oxygen using electron microscopy and X-ray diffraction.
Journal ArticleDOI
Pulsed laser ablation and deposition of thin films.
TL;DR: This overview traces the current physico-chemical understanding of the evolution of material from target ablation through to the deposited film, addressing the initial laser-target interactions by which solid material enters the gas phase.
Journal ArticleDOI
Growth of ZnO thin films—experiment and theory
Frederik Claeyssens,Colin L. Freeman,Neil L. Allan,Ye Sun,Michael N. R. Ashfold,John H. Harding +5 more
TL;DR: In this article, a periodic ab initio density functional theory calculation on thin films of ZnO which terminate with the (0001), (000), (100) and (110) surfaces is presented.
Journal ArticleDOI
Cavity ring-down spectroscopy
TL;DR: Cavity ring-down spectroscopy (CRDS) is a laser-based absorption spectrograph that is starting to find extensive application as a consequence of the very high sensitivity of the method compared with more traditional infrared spectrograms as discussed by the authors.
Journal ArticleDOI
The Role of πσ* Excited States in the Photodissociation of Heteroaromatic Molecules
TL;DR: In this article, high-resolution measurements of the kinetic energies of hydrogen atom fragments formed during ultraviolet photolysis of imidazole, pyrrole, and phenol in the gas phase confirm that N(O)−H bond fission is an important nonradiative decay process from their respective 1πσ* excited states.
